round down the counts of tokens to the nearest multiple of QUANT
(QUANT = QUANT_RATE * maxFreq, where QUANT_RATE is 0.01f
by default, and maxFreq is the maximum token frequency). If
maxFreq is higher than 1, then QUANT is always higher than 2 (which
means that tokens with frequency 1 are always discarded).

tokens, which frequency after quantization falls below QUANT, are discarded.

create a list of tokens and their quantized frequency, separated by spaces,
in the order of decreasing frequency.
